When restarting the MX2-A@ Inverter, wait for the Inverter power indicator to
go out before switching on again. Note the time to wait may vary depending
on the Inverter model.
Some DeviceNet Master Units in market may send Idle messages during spe-
cific events (start-up, PLC program mode, etc). In this case, consider to put
Action to Network Idle Mode (P048) to value 2 (no action).
Check the network related Inverter settings regarding DeviceNet node
address and other settings. Not doing so may result in unexpected operation.
The EDS file contains the access data for most of the Inverter's parameters.
This enables DeviceNet configurators such as CX-Integrator to configure the
Inverter.
The defaults of the parameters have been selected specifically for the Option
Board and not necessarily the same as the Inverter parameter's default value.
Please note that the write access of the Inverter parameters may depend on
the Inverter mode. Also make sure the Inverter is not in trip state before down-
loading the parameters.
During the parameter initialisation (Inverter parameter b180), operating the
Inverter is not prevented automatically and doing so may lead to unpredicted
behaviour.
Be sure to not operate the Inverter and do not write any Inverter parameter
during the parameter initialisation by Option Board or any other interface.
The slaves will be allocated data in the I/O Memory of the Master Unit or CPU
Unit the Master Unit is mounted to. They are allocated using one of the follow-
ing methods:
1. Fixed allocations
2. User-set allocations
For details about configuring the OMRON CJ1W-DRM21 and CS1W-DRM21
Master Unit's using CX-Integrator as configurator software, refer to DeviceNet
Unit Operation Manual (Cat. No. W380).
Turn ON the communications, inverter(s), and Master Unit or PLC power sup-
plies.
Confirm the Option Board's node number (inverter parameter P192) and
Default Connection Path (inverter parameter P046) are set properly. See
explanation in previous section.
Perform the Fixed allocation sequence as defined for the Master Unit.
Once the network is re-started with the new settings, check that the Option
Board LED indicators indicate proper operation: If everything is correctly con-
figured, both the MS (Module Status) LED and the NS (Network Status) LED
will be Green. Please refer to section 5-1 Troubleshooting Using the LED Indi-
cators for troubleshooting any configuration errors if the LED indicators are
displaying a different pattern.
Tip In case of any errors during configuring the network, please refer to SECTION
5 Troubleshooting and Maintenance.
